4. Operating Instructions
The chair offers several adjustment options to enhance your comfort:
- Seat Height Adjustment: Locate the lever under the right side of the seat. Pull the lever up to raise the seat. While seated, pull the lever up to lower the seat. Release the lever to lock the height.
- Rocking Function: The same lever used for seat height also controls the rocking function. Push the lever inwards to lock the backrest in an upright position. Pull the lever outwards to enable the rocking motion.
- Tilt Tension Adjustment: A round knob is located under the center of the seat. Rotate this knob clockwise to increase the tilt tension (making it harder to recline) or counter-clockwise to decrease it (making it easier to recline).
- Lumbar Support Adjustment: The lumbar support can be moved vertically. Adjust it to align with the natural curve of your lower back for optimal support.
- Headrest Adjustment: The headrest can be adjusted vertically to support your neck and head comfortably.
- Flip-up Armrests: The armrests can be rotated upwards by 90 degrees. This allows the chair to be pushed closer to a desk or to provide more space when not in use.
